(54) Title: MULTI-HARQ METHODS AND APPARATUS FOR CODEBLOCK GROUP BASED TRANSMISSIONS (57) : In an aspect of the disclosure an apparatus, e.g., a base station, maybe configured to receive, from a UE, ACK/NACK feedback indicating that a subset of CBGs of a set of transmitted CBGs failed to be properly decoded. The apparatus maybe further configured to retransmit the subset of CBGs based on the ACK/NACK feedback and transmit information indicating the CBGs being retransmitted. In one configura- tion, a TB of new data maybe transmitted with the retransmitted subset of CBGs in a subframe/slot. In an aspect, a UE may be configured to determine that one or more CBGs of a received set of CBGs failed to be properly decoded at the UE, and send ACK/NACK feedback indicating the one or more CBGs that failed to be decoded. The UE maybe further configured to receive a retransmission of CBGs in the set of CBGs, and information indicating the retransmitted CBGs.
